Description
Reference to related applications
The present application claims priority based on japanese patent application No. 2021-.
Technical Field
The invention relates to a printing apparatus, a printing control method and a recording medium.
Background
Conventionally, ink used for printing is a mixture of various solutes dissolved in a solvent such as water, and the state in which the solutes are dissolved in a uniform or nearly uniform state in the entire solvent is the state originally intended for use.
For example, in a printing apparatus (nail printing apparatus) that prints a design (design) on a nail or the like, a white base layer or the like may be formed on the nail surface before printing the nail design on the nail in order to develop a beautiful color without being affected by the nail color. A white base ink to be applied as a base contains a solute having a large specific gravity, such as titanium oxide, as a white component, and is likely to settle.
If printing is performed using an ink having a large solute deposition, there is a possibility that the quality of printing may be deteriorated due to, for example, a printing result in which color unevenness or horizontal streaks are caused by variations in ink concentration, or a problem in which ink cannot be normally ejected due to nozzle clogging.
As a method of stirring the ink to eliminate the settling state, for example, it is conceivable to shake the reservoir portion storing the ink by hand, but since the manner of shaking, the degree of application of force, and the like vary from person to person, there is a possibility that insufficient stirring or excessive shaking causes bubbles to be generated in the reservoir portion. Further, it is a work load for the user to perform the stirring by hand, which is a burden.
In this regard, japanese patent No. 5471358 discloses the following structure: a carriage that holds and moves a print head (a recording head in japanese patent No. 5471358) is provided with an agitation unit (a swing mechanism in patent document 1) and appropriately swings and agitates ink.
This makes it possible to stably stir the ink without bothering the user, and to maintain a state in which high-quality printing can be performed even with ink containing a solute having a large specific gravity, such as a base ink.
However, in the case where the carriage is provided with the stirring section as in patent document 1, the stirring section is also moved together when the print head is moved. Therefore, a space for their movement must be secured, resulting in an increase in the size of the apparatus.
Disclosure of Invention
The present invention has been made in view of the above circumstances, and an object thereof is to provide a printing apparatus, a printing control method, and a recording medium capable of stably performing high-quality printing.
In order to achieve the above object, a printing apparatus according to the present invention includes: a moving body that is capable of storing a storage unit that stores ink and performs a printing operation in a printing operation area in the apparatus; a moving mechanism that moves the moving body at least to the printing operation region and a stirring region provided outside the printing operation region; and a stirring section disposed in the stirring area and capable of stirring the ink in the storage section; when the moving member has moved to the agitation area by the moving mechanism, the agitation portion is locked to the moving member, and the ink in the storage portion is agitated.
Effects of the invention
According to the present invention, high-quality printing can be stably performed.

In the case of printing on the nail, the color development of the ink for design can be improved by applying the ink for base to the nail before the nail design is printed with the ink for design, and the printing (nail printing) with beautiful results can be performed.
Further, by providing both the base head 41a and the pattern head 41b, printing from the application of the base to the nail design can be automatically performed by 1 printing apparatus 100.
In the present embodiment, the print head 41 is simply referred to as a "print head" and includes a head 41a for a base and a head 41b for a pattern.
The ejection section 412 has a plurality of nozzle openings (not shown) for ejecting ink on a surface facing the nail surface, and ejects the ink stored in the storage section 411. The method of ejecting ink from the ejection section 412 is not particularly limited, and for example, the ink jet method ejection section is an ink jet method in which ink is made into fine droplets and ink is directly blown from a nozzle opening onto a nail surface as a printing surface of a printing target (nail) to perform printing. The print head 41 (the head 41a for the base and the head 41b for the pattern) performs a printing operation by ejecting ink from the ejection section 412 in the printing operation area Ar 1.
In the present embodiment, the print head 41 (the head 41a for the base and the head 41b for the pattern) is a carriage-mounted print head in which the storage section 411 and the ejection section 412 are integrally formed as a cartridge and are integrally mounted on a later-described holder 42.
Specifically, the print head 41 (the head 41a for the base and the head 41b for the pattern) having the storage section 411 and the ejection section 412 integrated with each other is held by the holder 42 and moved on the frame 451 by the head moving mechanism 49.
In the present embodiment, the print head 41 is movable in the XY direction on the base 20, and the head moving mechanism 49 includes an X-direction moving mechanism 45 that moves the print head 41 in the X direction and a Y-direction moving mechanism 47 that moves the print head in the Y direction.
As shown in fig. 3 and 4, the X-direction moving mechanism 45 includes a frame 451, an X-direction moving motor 46, and the like.
The Y-direction moving mechanism 47 includes a support portion 471 attached to the base 20, a Y-direction guide shaft 472 disposed in parallel to the left and right in the X-direction and attached to the support portion 471, a Y-direction moving motor 48, and the like.
The left and right ends of the frame 451 in the X direction are attached to left and right Y-direction guide shafts 472, respectively, and the frame 451 is moved in the Y direction along the Y-direction guide shafts 472 by the operation of the Y-direction moving motor 48.
The head moving mechanism 49 including the X-direction moving motor 46, the Y-direction moving motor 48, and the like is a moving mechanism that moves at least the storage section 411. The head moving mechanism 49 as a moving mechanism can move the storage section 411 (a movable body 410 described later that can house the storage section 411) to the stirring area Ar 2.
In the frame 451 constituting the X-direction moving mechanism 45, an X-direction guide shaft 452 and the like are provided along the X-direction. The movement guide 44 is attached to the X-direction guide shaft 452.
Fig. 5 is a side view of a main portion showing the stirring section, the moving body, and the periphery thereof. In fig. 5, illustration of the X-direction guide shaft 452 and the like constituting the head moving mechanism 49 is omitted.
As shown in fig. 5 and the like, the movement guide 44 has a shaft insertion hole 442 (see fig. 5 and 7) through which the X-direction guide shaft 452 is inserted, and moves along the X-direction guide shaft 452 in a state where the X-direction guide shaft 452 is inserted through the shaft insertion hole 442.
A carriage holding portion 43 for holding the carriage 42 on which the print head 41 is mounted is locked to the movement guide portion 44.
In the present embodiment, the movable body 410 is configured by including the storage section 411 of the print head 41, the carriage 42, and the carriage holding section 43 (the range of the movable body 410 is indicated by a broken line in fig. 5).
Fig. 6 is a perspective view of a main portion showing a configuration of a moving body and its periphery.
As shown in fig. 6, a locking portion 423 is provided on the rear side of the holder 42 (the apparatus rear side in the Y direction in fig. 6 and the like), and a locking receiving portion 431 that receives the locking portion 423 is provided on the holder holding portion 43 and the apparatus front side in the Y direction.
By the locking portion 423 being locked to the locking receiving portion 431, the print head 41 can move integrally with the holder holding portion 43 while being held by the holder 42.
Then, the holder holding portion 43 is locked to the movement guide portion 44, and the moving body 410 is attached to a conveyance mechanism such as the X-direction guide shaft 452 via the movement guide portion 44, and moves along the X-direction guide shaft 452 together with the movement guide portion 44 when the X-direction movement motor 46 operates.
The movement guide 44 allows some play, and maintains the locked state so that the moving body 410 does not come off from the movement guide 44 when the moving body 410 swings due to the operation of the stirring unit 30 (see fig. 10 and the like) described later. The structure of the movement guide 44 that allows the backlash is not particularly limited. For example, the backlash is allowed by providing play in the swing direction (in the up-down direction in the present embodiment) of the movable body 410 in the shaft insertion hole 442 through which the X-direction guide shaft 452 is inserted.
Further, even when the moving body 410 swings, the movement guide 44 does not come off the X-direction guide shaft 452.
Specifically, as described above, the shaft insertion hole 442 through which the X-direction guide shaft 452 is inserted is provided in the movement guide 44, and when the stirring section 30 is locked to the moving body 410, the movement guide 44 is locked to the main body locking section 451a provided on the apparatus main body side (the frame 451 in the present embodiment).
Fig. 7 is a main-part perspective view showing a positional relationship between the main-body locking part and the movement guide part of the frame 451, and fig. 8 is a main-part perspective view showing a state in which the movement guide part is locked to the main-body locking part. Fig. 9 is a main part perspective view in which the locking part of the body locking part and the locking part of the movement guide part in fig. 8 are enlarged.
As shown in fig. 7 to 9, in the present embodiment, the main body locking portion 451a is a convex portion provided on a side metal plate or the like of the frame 451 on the apparatus main body side. The movement guide 44 is provided with a recess 441 for receiving and locking the main body locking portion 451a at a position corresponding to the main body locking portion 451 a.
During the stirring operation by the stirring section 30, the main body locking section 451a is locked to the recess 441, and the movement guide section 44 does not largely shake with respect to the frame 451.
That is, only the moving body 410 (a member in a range surrounded by a broken line in fig. 5) is configured to swing during the stirring operation by the stirring section 30 so that the movement guide section 44 does not shake.
Therefore, even when the moving body 410 (the storage section 411 of the print head 41 included in the moving body 410) mounted on the frame 451 is swung to stir the ink, the influence of the swing of the moving body 410 by the stirring section 30 on the head moving mechanism 49 can be minimized, and the moving guide section 44 and the moving body 410 locked thereto can be normally conveyed after the stirring operation.
Here, the stirring section of the present embodiment will be described with reference to fig. 10 to 13.
As shown in fig. 3 and 4, the stirring unit 30 is disposed on the base 20 and in the stirring area Ar2, and can stir the ink in the storage unit 411. In the present embodiment, the stirring unit 30 stirs the ink by swinging at least the storage unit 411. The stirring unit 30 may be configured to stir the ink by a method other than the method of swinging the storage unit 411.
When the moving member 410 moves to the stirring area Ar2, the stirring section 30 and the moving member 410 are in a locked state (connected state). Then, in this locked state, the stirring operation of swinging the storage section 411 is performed.
Fig. 10 is a perspective view of a main portion of the stirring section locked to the movable body.
As shown in fig. 10, the stirring section 30 includes a support frame 31, an up-down slider 32 supported by the support frame 31, a stirring motor 33 as a power source, a motion conversion mechanism connected to the stirring motor 33 and converting the driving force of the stirring motor 33 from a rotational motion to a linear reciprocating motion, and the like.
The support frame 31 is fixed to the base 20 by screws 31a (see fig. 5, 11, and 13) or the like.
The lifting slider 32 is a plate-like member supported by the support frame 31. The elevating slider 32 is supported by the support frame 31, and can perform a stable linear motion without wobbling when reciprocating in the vertical direction.
The up-down slider 32 has a long hole 321 formed near the center thereof and extending in the lateral direction.
Further, a moving body engaging portion 322 projecting upward is provided on the upper portion of the up-down slider 32.
Fig. 11 is a perspective view of a main portion of the periphery of the locking portion between the stirring portion and the moving body according to the embodiment.
As shown in fig. 11 and the like, a recess 433 for receiving and locking the movable body locking portion 322 is formed in a holding portion lower portion 432 that is a portion of the holder holding portion 43 constituting the movable body 410 and that supports the holder 42 from below. When the moving member 410 including the storage portion 411 moves into the agitation area Ar2, the moving member locking portion 322 is fitted into the recessed portion 433 to be in a locked state, and the agitation portion 30 is locked (coupled) to the moving member 410.
When the movable body locking portion 322 is locked (that is, in the locked state), the stirring portion 30 and the movable body 410 are in the locked state, and the stirring operation of swinging the storage portion 411 (the print head 41 including the storage portion 411) is performed.
The movable body locking portion 322 is locked to and disengaged from the movable body 410 by the movement of the movable body 410 including the storage portion 411, and the state in which the movable body locking portion 322 is locked to the movable body 410 is released by the movement of the movable body 410 in the direction away from the agitation area Ar 2.
Fig. 12 (a) is an enlarged perspective view of a frame shown by a one-dot chain line in fig. 11, and fig. 12 (b) is a schematic view of a structure of a locking portion of the stirring section and the moving body. Fig. 13 is a perspective view of a main portion showing a locking state of the stirring section and the moving body according to the embodiment.
As shown in fig. 12 (b), the movable body locking portion 322 is provided with a locking convex portion 322a, and a recessed portion 433a into which the locking convex portion 322a is fitted is formed at a position corresponding to the locking convex portion 322a in the recessed portion 433. On the receiving side (left side in fig. 12 (b)) of the recessed portion 433a, R processing, chamfering processing, or the like is applied, and the movable body locking portion 322 is formed into a shape that facilitates the introduction into the recessed portion 433. The shapes of the locking convex portion 322a and the concave portion 433a are not limited to the illustrated example.
By forming the movable body locking portions 322 and the recessed portions 433 into such shapes, the movable body locking portions 322 are easily and smoothly locked to the recessed portions 433 only by the movement of the movable body 410 to the agitation area Ar2 (see fig. 13), and the agitation portion 30 is prevented from being detached from the movable body 410 during the agitation operation. When the moving member 410 moves in a direction away from the agitation area Ar2, the moving member locking portion 322 easily separates from the concave portion 433, and the locked state is released.
As described above, when the stirring section 30 and the moving body 410 are locked, the main body locking section 451a provided on the frame 451 side is locked to the recess 441 (see fig. 8) provided on the movement guide section 44. Therefore, in the present embodiment, the vibration of the stirring operation of the stirring section 30 is suppressed from affecting each part of the transport mechanism such as the X-direction guide shaft 452.
The stirring motor 33 is a driving source of the stirring unit 30, and has an output shaft 331 rotated by the rotation of the motor. The rotation direction of the stirring motor 33 may be either clockwise or counterclockwise. The rotation speed of the motor is appropriately set. It is conceivable that the stirring effect is improved as the rotation speed is higher, but the motor sound is also increased as the rotation speed is higher. Therefore, the rotation speed of the stirring motor 33 is determined according to the usage situation and the like. The rotational speed may be constant or variable.
A bearing member 332 having an eccentric shaft 333 eccentric to the output shaft 331 is attached to the output shaft 331 of the stirring motor 33.
The free end of the eccentric shaft 333 is disposed in the elongated hole 321 of the up-down slider 32, and the eccentric shaft 333 moves in the elongated hole 321 in response to the rotation of the stirring motor 33, whereby the up-down slider 32 linearly moves in the up-down direction.
In the present embodiment, a motion conversion mechanism for converting the driving force of the stirring motor 33 from the rotational motion to the linear reciprocating motion is configured by the bearing member 332 having the eccentric shaft 333 and the up-down slider 32 having the elongated hole 321.
In the embodiment, a description will be given by exemplifying a case where a scotch yoke (scotch yoke) mechanism is employed as the motion conversion mechanism, but the motion conversion mechanism is not particularly limited as long as it can convert the driving force of the stirring motor 33 from the rotational motion to the linear reciprocating motion. For example, another mechanism such as a slider crank mechanism may be used as the motion conversion mechanism.
As shown in fig. 5, even when the movable body locking portion 322 is locked to the recess 433 and the stirring portion 30 and the movable body 410 are in the locked state, the X-direction guide shaft 452 constituting the head moving mechanism 49 is inserted only into the shaft insertion hole 442 of the movement guide 44, and the movable body 410 including the storage portion 411 which swings by the stirring operation is configured not to be directly locked to the conveyance mechanism such as the X-direction guide shaft 452. Therefore, the head moving mechanism 49 is less susceptible to the influence of vibration caused by stirring, and can perform a highly accurate conveying operation even after the stirring operation.
The control device 80 mounted on the printing apparatus 100 is a computer including a control unit 81 (see fig. 2) configured by a processor such as a cpu (central Processing unit), not shown, and a storage unit 82 (see fig. 2) having a rom (read Only memory)821 and a ram (random Access memory) 822.
In the present embodiment, the control unit 81 mainly functions as the photographing control unit 811, the agitation control unit 812, the printing control unit 81, and the like.
The storage unit 82 is a non-transitory recording medium that stores a program or the like to be executed by the control unit 81. Various programs and various data for operating the printing apparatus 100 are stored in the storage unit 32, and functions of the control unit 81 as the photographing control unit 811, the agitation control unit 812, the printing control unit 81, and the like are realized by cooperation of the CPU of the control unit 81 and the programs stored in the ROM821 and the like of the storage unit 82.
The printing apparatus 100 includes the image pickup device 51 and the illumination device 52, and the image pickup control unit 811 controls the operation of the image pickup unit 50.
The imaging device 51 is a compact camera including a solid-state imaging element having pixels of about 200 ten thousand or more, a lens, and the like. The illumination device 52 is an illumination lamp such as a white LED.
The imaging unit 50 illuminates the nails of the fingers arranged in the printing operation area Ar1 with the illumination device 52. Then, the finger is photographed by the photographing device 51, and a nail image which is an image of the nail of the finger is obtained.
The image data of the image captured by the imaging unit 50 is acquired by the imaging control unit 811 and stored in the storage unit 82 or the like. When the printing apparatus 100 includes a communication unit that can communicate with an external terminal device or the like, not shown, the nail image acquired by the imaging unit 50 may be transmitted to the terminal device or the like via the communication unit.
The agitation control unit 812 controls the operation of the agitation motor 33 of the agitation unit 30 so as to agitate the ink stored in the storage unit 411. The stirring time (i.e., the time during which the stirring motor 33 is operated to perform the stirring operation) and the rotation speed of the stirring motor 33 during stirring are appropriately set in accordance with the usage situation.
The agitation time, the rotation speed, and the like may be set in accordance with an input instruction from the operation unit 12 or the like, or may be appropriately set by the agitation control unit 812 in consideration of the usage state of the ink (for example, elapsed time from previous printing, standing time of the ink, and the like), the type of the ink to be agitated, the remaining amount of the ink, and the like. The predetermined value may be set by default.
The agitation operation of the agitation unit 30 may be performed in response to an input of an operation instruction to the operation unit 12, or may be controlled by the agitation control unit 812 to be performed at a predetermined timing before the start of the printing operation.
The printing control unit 813 controls the printing unit 40 to perform printing processing.
Specifically, the operation of each motor (X-direction movement motor and Y-direction movement motor) of the head moving mechanism 49 is controlled based on the print data, and the operation of the ejection section 412 of the print head 41 (the head 41a for the base and the head 41b for the pattern) is controlled, so that the ink droplets are appropriately ejected.
The control device 80 may also function as a nail information detecting unit and a print data generating unit, for example, by detecting a range of a nail to be printed (i.e., a nail outline) by performing image analysis on the nail image acquired by the imaging unit 50, and generating print data by combining a desired nail design into the nail outline. Further, various correction processes may be performed on the print data. The detection of nail information, the generation of print data, the correction of print data, and the like may be performed by an external terminal device, and the control device 80 of the printing device 100 may receive the final print data and perform the printing process.
Next, the operation of the printing apparatus 100 and the printing control method according to the present embodiment will be described.
When printing is performed by the printing apparatus 100, print data for printing a desired nail design on a nail is prepared. Then, if a start of printing is instructed by an input to the operation unit 12 or the like, the control unit 81 operates the Y-direction movement motor 48 of the head movement mechanism 49 to move the frame 451 of the X-direction movement mechanism 45 toward the front side of the apparatus in the Y-direction (for example, the state shown in fig. 3).
When the frame 451 moves to the forefront in the Y direction, the control unit 81 then operates the X-direction movement motor 46 to move the movable body 410 (i.e., the carriage 42 on which the print head 41 including the storage unit 411 is mounted) in the frame 451 to the agitation area Ar 2. In the present embodiment, the movable body 410 is moved to the left end portion in the X direction (for example, the state shown in fig. 4).
When the movable member 410 moves to the agitation area Ar2, the movable member engagement portion 322 provided on the lifting slider 32 of the agitation portion 30 is engaged with the recessed portion 433 provided on the holding portion lower portion 432 by the movement, and the agitation portion 30 and the movable member 410 are engaged with each other (see fig. 13 and the like).
At this time, the main body locking portion 451a provided to the frame is received in the concave portion 441 of the movement guide portion 44 to which the holder 42 is locked, and the movement guide portion 44 is locked to the frame 451 as a mechanism on the apparatus main body side (see fig. 6, 8, and the like). In this state, the agitation control unit 812 operates the agitation motor 33 of the agitation unit 30 to swing the storage unit 411, thereby performing an agitation operation of the ink in the storage unit 411.
Fig. 14 (a) to (d) are front views of the stirring section showing the operation of the elevating slider of the stirring section.
Fig. 14 (a) shows a state in which the eccentric shaft 333 disposed in the long hole 321 of the up-down slider 32 is at the lowest position. The height of the upper end of the lifting slider 32 (i.e., the upper end of the movable body locking portion 322 locked to the movable body 410) at this time is the position indicated by the broken line "H1".
Fig. 14 (b) shows a state in which the stirring motor 33 has rotated 90 degrees clockwise from the state in fig. 14 (a). At this time, the eccentric shaft 333 moves to the left end in the long hole 321, and the entire up-down slider 32 is pushed up in accordance with the rise of the height position of the eccentric shaft 333. The height of the upper end portion of the lifting slider 32 (the upper end portion of the movable body locking portion 322) at this time is the position of "H2" indicated by the broken line, and is higher than the state "H1" (indicated by the one-dot chain line in fig. 14 (b)) shown in fig. 14 (a).
Fig. 14 (c) shows a state in which the stirring motor 33 is rotated further 90 degrees clockwise (180 degrees from the state of fig. 14 (a)) from the state of fig. 14 (b). At this time, the eccentric shaft 333 moves to the center portion in the long hole 321, and the height position of the eccentric shaft 333 is highest. The entire up-down slider 32 is further pushed up in accordance with the rise of the height position of the eccentric shaft 333, and the height of the upper end portion of the up-down slider 32 (the upper end portion of the moving body engagement portion 322) at this time becomes the position of "H3" indicated by the broken line, and becomes highest as compared with the state "H1" (indicated by the one-dot chain line in fig. 14 (c)) shown in fig. 14 (a).
Fig. 14 (d) shows a state where the stirring motor 33 is rotated further 90 degrees clockwise (270 degrees from the state of fig. 14 (a)) from the state of fig. 14 (c). At this time, the eccentric shaft 333 moves to the right end in the long hole 321, and the height position of the eccentric shaft 333 is the same as that in fig. 14 (b). The height position of the eccentric shaft 333 becomes lower than the state shown in fig. 14 (c), and the entire up-down slider 32 also moves down, and the height of the upper end portion of the up-down slider 32 (the upper end portion of the moving body engagement portion 322) at this time becomes the position indicated by the broken line "H4", and becomes the same height as the state "H2" shown in fig. 14 (b).
Then, if the stirring motor 33 rotates further 90 degrees clockwise, the height position of the eccentric shaft 333 returns to the state of fig. 14 (a), and the height of the upper end portion of the up-down slider 32 (the upper end portion of the moving body locking portion 322) also decreases to the state of fig. 14 (a). By repeating such operations, the up-down slider 32 repeats up-down movement, and the moving body 410 to which the up-down slider 32 is locked swings (vibrates) up and down, thereby stirring the ink in the storage section 411.
In the present embodiment, the storage section 411 and the discharge section 412 constituting the movable body 410 are integrated. Therefore, if the storage section 411 swings, there is a possibility that ink droplets or misty ink may drop from the ejection section 412. In this regard, since the ink receiving portion 22 is provided in the agitation area Ar2, ink droplets and the like dropped from the ejection portion 412 are received by the ink receiving portion 22, so that the inside of the apparatus is not contaminated.
If the ink stirring operation is performed for a predetermined time, the control section 81 stops the stirring operation and shifts to the printing operation.
Further, the maintenance of the print head 41 may be performed after the stirring operation and before the shift to the printing operation. For maintenance, for example, the state of the nozzles of the ejection section 412 may be adjusted by forcibly ejecting ink from the ejection section 412 to the ink receiving section 22, and for example, in the case where a maintenance area is separately provided, a maintenance operation such as cleaning or wiping may be performed by moving the printing head 41 into the maintenance area after the stirring operation and before the printing operation.
During the printing operation, the control unit 81 moves the print head 41 into the printing operation area Ar1 by operating the motors (the X-direction movement motor 46 and the Y-direction movement motor 48) of the head movement mechanism 49, ejects ink from the ejection unit 412 of the print head 41 in accordance with print data, and applies printing to the nail surface.
In the present embodiment, first, a base ink is ejected from the base head 41a to form a base layer on the nail surface. Although the white component and the like are easily separated and precipitated in the base ink, the white component and the like are almost uniformly dispersed by stirring in the stirring section 30. Therefore, a base layer having no beautiful result such as concentration unevenness can be formed. In addition, since the stirring (oscillation) is performed together with the storage part 411 including the holder 42, the stirring effect is high compared to a method of vibration or the like.
When the base layer is formed, the control section 81 ejects the pattern ink of each color from the pattern head 41b onto the base layer to perform printing of the nail-art pattern, and terminates the printing process.
As described above, in the present embodiment, since a pattern can be printed on the base layer without density unevenness or the like, nail print of high quality can be performed.
As described above, according to the present embodiment, the printing apparatus 100 includes: a moving body 410 including at least a storage portion 411 that stores ink; a head moving mechanism 49 as a moving mechanism for moving the storage section 411; and an agitation unit 30 disposed in an agitation area Ar2 outside a printing operation area Ar1 provided in the apparatus and capable of agitating the ink in the storage unit 411; when the moving member 410 moves into the agitation area Ar2, the agitation unit 30 and the moving member 410 are locked, and the agitation unit 30 agitates the ink in the storage unit 411.
This makes it possible to automatically stir the ink without bothering the user. During the stirring, the moving member 410 moves to the stirring area Ar2 and is locked to the stirring section 30. This allows the ink in the storage section 411 to be stirred without moving the stirring section 30 itself. Therefore, it is possible to avoid an increase in the size of the apparatus and to cope with a situation where the motor of the head moving mechanism 49 does not have a high output.
Further, since the ink can be appropriately stirred in the printing apparatus 100 as described above, even when printing is performed using ink containing a solute having a large specific gravity such as titanium oxide (in the present embodiment, ink for a base such as white ink), the ink can be stirred without taking out the storage unit 411 from the apparatus, and an appropriate state such as no density unevenness can be maintained. Therefore, high-quality printing can be stably performed.
In the present embodiment, the stirring unit 30 stirs the ink in the storage unit 411 by at least swinging the storage unit 411.
This enables efficient stirring of the ink.
In the present embodiment, the ink jet head further includes an ejection unit 412 that ejects the ink stored in the storage unit 411, and the storage unit 411 and the ejection unit 412 are integrally configured.
In the case where the print head 41 is of an integrated cartridge (cartridge) type, a configuration such as connecting the storage portion and the ejection portion with a supply tube is not necessary, and the device configuration can be simplified.
In the present embodiment, the agitation area Ar2 includes an ink receiving portion 22 that receives ink droplets generated from the ejection portion 412.
When the integral cartridge type print head 41 is agitated, there is a possibility that ink droplets may drop from the ejection portion 412 during or after the agitation operation. In this regard, since the ink receiving portion 22 is provided, even if ink droplets are dropped, the inside of the apparatus is not contaminated.
In the present embodiment, the stirring unit 30 includes the moving body locking unit 322 that is locked to and released from the moving body 410 by the movement of the moving body 410 including the storage unit 411, and when the moving body locking unit 322 is in the locked state, the stirring unit 30 and the moving body 410 are in the locked state, and the storage unit 411 is swung to stir the ink in the storage unit 411.
Thus, the stirring section 30 and the movable body 410 can be locked and unlocked only by moving the movable body 410 without providing a separate complicated structure.
In the present embodiment, the movable body 410 is locked to the movement guide 44 that moves along the X-direction guide shaft 452 and moves together with the movement guide 44, and the movement guide 44 is locked to the main body locking portion 451a provided on the frame 451 that is the mechanism portion on the apparatus main body side when the movable body locking portion 322 is in the locked state.
In this way, by indirectly attaching the moving body 410 to the head moving mechanism 49 via the movement guide 44, when the moving body 410 swings by stirring, the vibration of the movement guide 44 is suppressed, and the influence on the head moving mechanism 49 can be suppressed. Therefore, even if stirring is performed in the apparatus, high-precision conveyance can be maintained.
Further, by locking the movement guide 44 to the frame 451 during the stirring, the movement guide 44 can be prevented from being detached from or displaced from the X-direction guide shaft 452 due to the vibration caused by the stirring.
In the present embodiment, the stirring section 30 includes the stirring motor 33 and a motion conversion mechanism for converting the driving force of the stirring motor 33 from the rotational motion to the linear reciprocating motion, and the storage section 411 is swung by the driving force of the stirring motor 33 converted into the linear reciprocating motion by the motion conversion mechanism.
This enables the storage section 411 to be effectively swung even in a narrow apparatus, and ink can be sufficiently stirred.
In addition, the maintenance step may perform maintenance of the print head at least after the stirring operation and before the shift to the printing operation.
Therefore, even in the case of the print head 41 in which the ejection portion 412 and the storage portion 411 are integrally configured, and if the storage portion 411 is swung, ink droplets are ejected from the ejection portion 412, printing can be performed in an appropriate state, and high-quality printing can be achieved.
While the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various modifications can be made without departing from the scope of the invention.
For example, in the present embodiment, the case where the motion conversion mechanism that converts the driving force of the stirring motor 33 from the rotational motion to the linear reciprocating motion converts the rotational motion to the linear reciprocating motion in the vertical direction has been described as an example, but the motion conversion mechanism may be a mechanism that converts the rotational motion to the linear reciprocating motion in the horizontal direction, or the like.
In the present embodiment, the case where the stirring section 30 includes the stirring motor 33 is exemplified, but the motor as the driving source of the stirring section 30 is not limited to the stirring motor 33.
For example, a motor (for example, the X-direction moving motor 46) or the like provided in the head conveying mechanism 49 may be configured to operate also as a drive source of the stirring section 30. In this case, the number of motors provided in the device can be reduced, and the device can be further reduced in size and weight.
The agitation area Ar2 is not limited to the position shown in the present embodiment as long as it is an area outside the printing operation area Ar 1.
For example, the region at the left end in the X direction and behind the apparatus may be set as the stirring region Ar2 in which the stirring section 30 is provided.
In the present embodiment, the ink receiving portion 22 is provided in the agitation area Ar2, but the provision of the ink receiving portion 22 is not essential.
For example, when the agitation area Ar2 is provided at the rear of the apparatus as described above, a maintenance unit for performing maintenance of the print head 41 may be provided in or around the agitation area Ar 2. The maintenance unit includes, for example, a cleaning unit that receives ink forcibly ejected from the nozzles, a wiping unit that wipes the ejection unit 412 and removes ink adhering to the nozzle openings, and the like. The cleaning unit may function as an ink receiving unit for collecting ink droplets and ink mist generated by the stirring operation.
In the present embodiment, the case where the printing apparatus 100 includes both the base head 41a and the pattern head 41b has been described as an example, but the printing apparatus is not limited to this. For example, the printing apparatus may be a dedicated machine for printing a substrate, which is provided with only the substrate head 41a for storing the substrate ink to be stirred by the stirring unit 30. In this case, after the substrate is printed, the finger is set in a printing apparatus having a pattern head for printing various color inks (i.e., pattern inks) to print a nail design.
In the present embodiment, the case where the base head 41a and the pattern head 41b are held by 1 carriage 42 and moved integrally is exemplified, but the configuration of the printing portion 40 is not limited thereto.
For example, the substrate head 41a and the pattern head 41b may be held by different holders and may be independently movable. In this case, when the ink to be stirred is only the base ink, only the stirring portion 30 for the storage portion storing the base ink may be stirred, or only the holder holding the base head 41a may be locked to the stirring portion 30 during the stirring operation to stir.
In the present embodiment, the case where the printing apparatus 100 is configured to be able to perform the printing operation by itself is exemplified, but the printing apparatus 100 is not limited to the configuration shown here.
For example, the printing system may be configured in cooperation with an external terminal device (e.g., a smartphone or a tablet terminal). In this case, for example, almost all of the processing other than the ink stirring operation and the printing operation, such as selection of a nail art, generation of print data, and the like, may be performed on the external device side such as the terminal device.
While the embodiments of the present invention have been described above, the scope of the present invention is not limited to the above embodiments, and includes the scope of the invention described in the claims and the equivalent scope thereof.
